Environment: Fix feature detection for Ipad

[tmcconechy]

Describe the bug
in ipad ios 13 the feature detection changed:

I opened Settings -> Safari -> Request Desktop Website -> All websites. That option is enabled by default. I disabled it and the proper User Agent is now displayed.

Mozilla/5.0 (iPad; CPU OS 13_0 like Mac OS X) AppleWebKit/605.1.15 (KHTML, like Gecko) Version/13.0 Mobile/15E148 Safari/604.1

IMO it should be disabled by default and if a user enables it a modal window should be displaying indicating not all web sites will be supported properly. Or maybe you may consider to add the iPad word to the first user agent to allow us to detect if it is an ipad emulating safari desktop or enable mouse event emulation, because I think when it is released several websites will fail.

To Reproduce

Steps to reproduce the behavior:

1. Go to http://localhost:4000/components/environment/example-browser-specs.html
2. Compare this page on ipad 11, 12, 13, 14 -> 13 and 14 are wrong

Expected behavior
Correct detection on ios 13 and 14

Platform

• Device: ipad
• OS Version: 13/14
• Browser Name: safari
